9. Auto Test
The auto test enables the system to automatically test whether functions of various modules are normal, including the
screen, sensor, voice, face, keyboard and clock tests.
1. Test Screen: The device automatically tests the display effect of the color TFT display by displaying full color, pure
white and pure black and checks whether the screen displays properly. You can continue the test by touching the
screen or quit by pressing [Exit].
2. Test Voice: The device automatically tests whether the voice files are complete and the voice quality is good by
playing the voice files stored in the device. You can continue the test by touching the screen or quit by pressing
[Exit].
3. Test Face: The device automatically tests whether the camera works properly by checking whether the collected
face images are clear and acceptable. Press [Exit] to quit the test.
4. Test Time: The device tests whether its clock works properly by checking the stopwatch of the clock. Touch the
screen to start counting, and touch it again to stop. Check whether the counting is accurate. Press [Exit] to exit the
test.
5. Calibration: You can perform all the menu operations by touching the screen with one of your fingers or a stylus.
When the touch screen is less sensitive to the touch, you can perform a screen calibration.
Calibration

and the system automatically returns to the main menu. If the calibration fails, the
system recalibration will start from Step 3.
